Other actions.--The Committeeon Classificationand Nomenclatureanticipates publication of a 2-volume7th Edition of the Check-listof North American Birds in 1993 consistingof a complete update and treatment of subspecies.Supplements to the 6th Edition are projectedfor publication in July 1987,1989, and 1991.In res•nse to the lackof growthin endowment,a "SecondCentury Endowment Campaign" is to •gin soon.The Council approved a new publication venture, 7AA consistingof speciesaccounts of North Americanbirds in loose-leaffascicle form. PeterStettenheim was appointedEditor. It is anticipatedthat 50 accountswill be prepared in the next two years, eachby an authorwith extensivefield experiencewith the speciesdescribed. A SpecialCommittee on Humane Handlingof Birdsin the Field, includingrepresentation from the Cooperand Wilson OrnithologicalSocieties, will produceguidelines for the humanecare of birdsduring field research. Councilmerged the Herbert and Betty CarnesCommittee and the ResearchAwards Committee and establishedguidelines for making researchand travel awards.Student Membership Awards will be discontinued.

ATTENDANCE Registrationat the meeting totaled 317 (including 195 members,105 students,and $9 spouses and guests)from 40 states,the District of Columbia,Puerto Rico, $ provincesof Canada,Brazil, the PeoplesRepublic of China, Israel, Japan, Peru, and Venezuela.The largestrepresentations were from Mississippi($8), Florida (20), Louisiana(20), California (16), and Texas (16).

SPECIAL EVENTS On the eveningof 19 AugustFellows and Council Membershad dinner at the University Inn. During the meeting,tours were offered to variouslocal pointsof interestincluding the M.S.U. Dairy ScienceLaboratory, School of Veterinary Medicine,A. B.

FIELD TRIPS Early morning birding trips were organizedby Malcolm Hodgesand Danny Ingold. On 22 August,members enjoyed a canoetrip led by JeromeJackson down the Tombigbee River, including passagethrough the lock and dam at Columbus,Mississippi. On August22-25, memberspartic- ipated in a trip to the MississippiGulf coastand Horn Island, a part of Gulf IslandsNational Seashore.The trip was organizedby Ted Simonsand JeromeJackson and ended with dinner at the home of Dr. and Mrs. C. D. Taylor of PassChristian. Transportation to Horn Island was provided by the U.S. National Park Service.

PUBLIC SESSIONS General paper sessionswere held in the Student Union on the campusof MississippiState University.At the openingsession on the morningof 19 August,President Donald W. Zacharias of MississippiState University welcomed the A.O.U. and PresidentFrances C. Jamesresponded for the Union. SecretaryRussell reported on actionstaken at the severalbusiness meetings and JeromeA. Jackson,Co-chair of the Committee on Local Arrangements,made brief commentsas did Robert M. Zink, Chair of the ScientificProgram Committee. Symposiawere held on the evolutionarysignificance of geographicvariation and on migratorybirds in the tropics.There was a workshopon theanalysis and interpretationof aviangrowth data. A plenarylecture on "Current statusof waterfowlpopulations and currentneeds" was given by Dr. LaurenceR. Jahn,Wildlife ManagementInstitute, Washington, D.C.

RESOLUTIONS Sixresolutions were adopted at the GeneralSession held Wednesday afternoon, 20 August.The resolutionsare distributedappropriately to individualsand organizations,including governmental agencies.Resolutions adopted are as follows:

Resolution 1: PIPING PLOVER CONSERVATION RECOGNIZING that the Piping Plover (Charadrius melodus)has suffereda radical continent- wide decline in numbers, and WHEREAS this declinehas been recognizedby the United StatesFish and Wildlife Serviceof the Departmentof the Interior by classificationof thisspecies as "Endangered"in the Great LakesRegion and as "Threatened"in the restof its range,and WHEREAS the Committeeon the Statusof EndangeredWildlife in Canadaand the concerned provincialand federal agencies in Canadahave recognized this species as endangered through- out Canada, and 14AA

RECOGNIZING that both the United Statesand Canada are preparingrecovery plans for this species,and RECOGNIZING that this speciescan be preservedas part of our naturalheritage only if swift, decisive,and cooperativeinternational action is taken, THEREFORE BE IT RESOLVED that the AmericanOrnithologists' Union urgesthose officials involved with theserecovery efforts to assesscontinent-wide populations, winter and summer; preserveareas with viablepopulations and amelioratethe impactof humanintrusion on the breedingand winteringgrounds; and determinethe racialdistinctness of populations.

Resolution 2: IMPACT ON AVIAN SPECIES OF ENVIRONMENTAL CONTAMINATION CAUSED BY THE CHERNOBYL ACCIDENT WHEREAS the unfortunate,recent reactor accident at the Chernobylnuclear power plant provides a historicopportunity to investigateshort- and long-termbiological impacts of radioactive contaminationon plant and animal populations,and WHEREAS recentmeetings with Europeanornithologists confirm that extensiveradioactivity has reacheda numberof habitatswhere ornithological studies have beenin progress, THEREFORE BE IT RESOLVED that the American Ornithologists'Union stronglyurges concerned agenciesand governments,including the InternationalAtomic Energy Agency, to monitorand studythose areas of avian ecology,behavior and migration,that may be affected by this radioactivecontamination.

Resolution $: PROVISIONS TO BE INCLUDED IN BILLS TO BAN THE SALE OF WILD-CAUGHT BIRDS RECOGNIZING that longstandingproblems associated with the commercialtrade in live wild birdshave generated the needfor strictertrade controls,and RECOGNIZING that commercialtrade threatensthe survivalof many bird speciesin the wild, and WHEREASin thepast year several states have reviewed and either accepted or rejectedlegislation banningthe importationand/or saleof live wild-caughtbirds, and RECOGNIZING that suchstate bills shouldcontain certain provisions to allow for scientificand educationalpurposes that are not now providedby thesebills, THEREFORE BE IT RESOLVED that the American Ornithologists'Union recommendsthe followingprovisions be includedin any suchstate bills: (1) Appropriateexemptions for scientificand educationalinstitutions; (2) Appropriateexemptions for licensedprivate aviculturists or, if licensesare not required, thoseaviculturists with acceptablestandards of humanecare and scientificrecord-keeping; ($) A listof exemptedspecies of birdsbased on the listincluded in the New YorkRegulations "Sale of Wild BirdsI.D. No. ENV-$9-856-00051-P,"with specialconsideration given to endangeredand threatened species to enhancethe probabilityof theirsurvival; (4) A methodfor addingor deletingspecies from the exemptedspecies list within a reasonable time under specifiedjustifiable circumstances; (5) Scientificidentification of birdsand adequaterecord-keeping systems; (6) A clear definitionof terms usedin the legislation.

Resolution 4: TO ESTABLISH AN INTERNATIONAL RESERVE SYSTEM TO PROTECT MIGRATORY SHOREBIRDS IN THE WESTERN HEMISPHERE WHEREASmany species of NorthAmerican shorebirds depend upon a smallnumber of essential migratorystopover places for theirstaging and feeding during annual migration between the Northern and Southernhemispheres, and WHEREAS Federal,State, and Provincialwildlife agenciesare responsiblefor the protectionand managementof the shorebirdresource under the termsof the MigratoryBird TreatyAct, and WHEREAS the World Wildlife Fund-U.S., the International Associationof Fish and Wildlife Agencies,the International Council for BirdPreservation-Pan American Section, the Academy of NaturalSciences of Philadelphia,the Wader StudyGroup, and a numberof otheragencies and institutionshave shownan interestin developinga networkof localities,to be known as the WesternHemisphere Reserve System, that are essentialto the survivaland well-being of shorebirds, 15AA

THEREFORE BE IT RESOLVED that the American Ornithologists'Union encouragesefforts of countriesand agenciesto developan internationalshorebird management plan for identifying and preservingessential shorebird habitat and for establishinga seriesof reservesthroughout the Western Hemisphere.

Resolution 5: ESTABLISHMENT OF THE NATIONAL MARINE PARK OF FERNANDO DE NORONHA WHEREAS Fernandode Noronhais the main islandof an archipelagolocated 360 kilometersoff the coastof NortheasternBrazil and is inhabited by three endemic land bird taxa and ten speciesof nestingseabirds, and RECOGNIZING that islandavifaunas are particularlyfragile, and the historyof their decimation by man has been a tragic story, and RECOGNIZING that Fernandode Noronha is classifiedas a Federal Territory and managedby the Air Force Ministry of Brazil, and the possibilityfor touristdevelopment is great, THEREFORE BE IT RESOLVED that the American Ornithologists'Union supportsthe efforts of Brazilian conservationists to establish Fernando de Noronha as a National Marine Park in order to enforce protectionfor the wildlife of the island.

Resolution 6: COMMENDATION WHEREAS The American Ornithologists'Union has held its One Hundred and Fourth Stated Meeting on the campusof and at the invitationof MississippiState University and RECOGNIZING that the Local Committee on Arrangements,under the capabledirection of JeromeA. Jacksonand BetteJ. S.Jackson, provided us with an exceptionallydiverse assemblage of exhibits,special events, tours, field trips,and eveningsocial gatherings, and RECOGNIZING that the Committeeon the ScientificProgram under the equally capable direction of Robert M.
